is provided at opposite .sides ofthe split portion irith ears 5receiving a clamping screiiY G. The perforation o t' one ot'the. ears l5 isthreaded to engage, With the threads of l the screw. and the latterisadapted to draw l the opposite sides ot' the socket tightly into ltrietional engagement with the trolley pole. l l'he socket and the poleare preferably i pierced by a transverse bolt or pin G to prel rent" thesocket from turning on the pole. l ',lhe trolley head is provided at thevfront ot' l its `upper end with a recess 7, formino' side l flanges orWalls 8 and receiving a bractet 9.I l which is pivoted in therecess byAa pin 10, l'or other `suitable fastening device, piercing l 4the wallsS and the lower end of the bracket. ,The bracket. which is adapted toswing upward and downward, is yieldably sup n ported by a coiled spring11, and it isof l angular form being composed of a lower straight stem12. a rearwardly extending intermediate. portion 13 and anfupwardly`projecting arm 14. The stem and thearm extend in oppositedirectionsjtrom the intermediate connecting portion 153, and aredisposed at approximately right angles to the same. The intermediateportion 13 and the arm 14 providean approximately l..- shaped upperportion to the bracket. The arm 3 of the trolley head is recessed to provide a cylindrical seat 15 for the coiled spring, and'ity has a terminaleye 16 for the vattachment of a cord or rope. VThe upper end ot thespring is .suitably secured to the lower face o the intermediateconnecting portion of the bra-siret integral hooli-shapet'i lug llt. aninner projection 15". and a screw 1W. which also se; cures a plate li'lo the lower tace of the counecting` portion of. the bracket. Thehookshaped lug par'ially embraces the upper coil- -of the. supportingspring 11. andthe screw 16L maintainsI the upper coil' in such engagement.. The spring by yieldahly supporting the pimally mounted bracket?,lcooperates with thix 'uca-:l and the bracket to form an eX- tensililctrolley attachment. which maintainC lthe trolley ivheel '1H iuengagement l with the trolley wire. and through the vielding audextensible character olf-thc attachestrato at Vone side by the said lugaforli pirotally mounted on the bracket and adapted to reing a trolleyhead. lun-'ing a rearwardly er tending arm, a 'bracket pivoted to thetrolley head in advance of the rear ardly entendingrarm'and having aeulitz'antially laehaped portion located above the Sai Ie and forming anupwardly projecting arm, a spring in terposed between the rearwln'dlyextending arm of the head and the bracket 'for urging the .latterupwardly, a trolley wl1eel-receiving forli mounted on the upwardlyprojecting arm of the bracket and arrange( at an inclination to thetrolley wire-when the trolley is in engagement 'with th Same and havingan axial rotary movement, and anotl'ler spring connected ivitli the'fork and with thev bracket for maintaining a trolley Wheel in alinementwith the trolley wire.
